PRECAUTIONS

To ensure trouble-free operation, please observe the following precautions:

Optical communications are easily affected by external light sources, weak batteries, transfer

distance, transfer angle, etc.

Any of these conditions may cause a data transfer failure, incomplete or missing data. Make

sure that the wireless interface is away from direct sunlight and other strong light source.

 Do not terminate arbitrarily during file transfer process between IR100SD and computers

until finished. Otherwise IR100SD internal data integrity may be damaged, which is due to

the violation of IR100SD’s.

 Do not expose the unit to moisture, as this will damage the internal circuitry.

 Do not expose the unit to extreme temperatures. It should not be placed in direct sunlight or

in a closed vehicle, neither should it be placed near heaters nor other heat sources.

 Do not store the unit in a humid or dusty place.

 Use a soft, dry cloth to clean the unit. Do not use a wet cloth or any solvent.

 Do not drop the unit or handle the unit carelessly.

CAUTION:

 Never touch the pins of computer connection terminal. The internal circuits can be damaged

by a static electricity discharge. If this device requires any servicing, use only an ACTiSYS

service dealer, an ACTiSYS approved service facility, or an ACTiSYS repair service.

 When exchanging data with host computer, be sure the appropriate serial communication

port is available and is not in conflict with other peripheral device or software.

2. OVERVIEW

The ACT-IR100SD is a high-integration IrDA Intelligent dongle. It provides a serial interface to a host

device that intends to have Infrared communication capability. The host device can be any equipment or

device that needs to communicate with IrDA enabled portable or tablet PC, PDA, cellphone and hand

held data terminal, via IrDA protocol with only a wired serial interface. The ACT-IR100SD will handle all

the detail about IrDA protocols. It sends and receives only user data to and from the host device via the

wired serial interface with hardware flow-control. IrDA has two modes; one is Primary, and the other is

Secondary. The difference between them is that a Primary mode device initiates discover, connection

sequence and negotiate IrDA protocol parameters to Secondary mode device; while Secondary mode

device always waits for commands from Primary mode device. Both modes can run different protocols,

and both may send or receive user data. ACT-IR100SD supports both modes. When IR100SD is set to

Primary mode, user can choose IrCOMM, IrLPT or OBEX PUT/GET server to be Primary protocol via a

simple PC utility. Fig.1 is the system diagram.

3. ARCHITECTURE OF ACT-IR100SD

The mandatory IrDA protocol layers, IrLAP and IrLMP (including IAS) are handled by ACT-IR100SD, In

addition, TinyTP, IrCOMM, IrLPT and OBEX transport are also included.

The incoming/outgoing IrDA user data payload are buffered and then transferred to/from the host. The

baud rates of IrDA traffic and host interface are independent of each other. The flow controls of IrDA

traffic and host interface are also independent of each other.

4. HOST INTERFACE

The host interface of ACT-IR100SD is a full-duplex asynchronous RS232 DB9M connector. The following

table is the signals of DB9M connector. It can be treated as DTE. The data bytes are transmitted via TXD

pin and received via RXD. Each data byte consists of one start bit (0), 8 data bits (LSB first, MSB last), a

stop bit (1) and no parity bit.

Implementing H/W flow control signals in host end is recommended. Since ACT-IR100SD is a buffer

limited dongle. Without flow control will probably cause data loss sometimes. The H/W flow control

relative signals are: DTR, RTS, DSR and CTS, which are defined exactly as RS232 DTE interface.

4.1 Host Interface Signals

ACT-IR100SD host interface consists of three output signals and five input signals. All these signals are

low active. That is, they are at 0V when active and at VCC level when inactive. When an inverting RS232

level converter is used, the corresponding RS232 level signals are high active. That is, they are at +12V

nominal when active and at –12V nominal when inactive.

4. /TXD: serial data output.

2. /RXD: serial data input.

3. /RTS: output. When hardware flow control is enabled. Active /RTS means /RXD is ready to

receive. Inactive /RTS means /RXD is not ready.

4. /CTS: input. If hardware flow control is enabled, /CTS must be driven active to allow /TXD and

inactive to forbid /TXD. If hardware flow control is disabled, /CTS is optional.

5. /DSR: input. If connection control is enabled, /DSR must be driven active to allow IrDA connection

and inactive to forbid a new connection or terminate an existing connection. If connection control

is disabled, /DSR is optional.

6. /DTR: output. If connection control is enabled, active /DTR means an IrDA connection is made.

Inactive /DTR means there is no connection.

7. /CD: input. Optional.

8. /RI: input. Optional.

5. OPERATING IN ACT-IR100SD

5.1 How To Connect IR100SD With Host Device:

IR100SD uses a standard RS232 DTE port to connect with the host. If the host device is a Modem

like device and has a RS232 DCE port, then use a "straight cable". That is, connect the signals with

the same name from one side to the other.

All the operating procedures of IR100SD are triggered by DSR signal from HOST, (DSR for IR100SD

is an input signal.) except DSR is ignored by PC utility, see section 5.2 below. When DSR is pulled

high level (RS232 level) by HOST, IR100SD will send out discovery frames to outside and try to find

some other IrDA devices if IR100SD is set to Primary mode. Or it is ready to receive discovery frame

from another Primary device outside if IR100SD is set to Secondary mode. It depends on what mode

is operating in IR100SD.

When IR100SD is connecting to another IrDA device successfully via IR, it will pull DSR signal to high

(RS232 level), which also means that Host can send and receive data frame to and from another IrDA

device. When DSR is pulled to low, it means that IR link is not established anymore.

5.2 How To Configure The Role Modes And The Other Parameters In ACT-IR100SD:

Since ACT-IR100SD supports Primary, Secondary and several parameters, Comset_IR100SD.exe is

an application associated with the dongle for customers to configure the dongle themselves.

Please attach IR100SD dongle in PC then execute Comset_IR100SD.exe in Windows system. It will

show three pages of parameters for change. After any parameter is changed, you have to press

“send” button on every page you change first. Then press “Save Config into Flash” so that

parameters can be configured successfully.
